With these time series:
Present a line graph for the time series. Describe the time series in terms of the observable components (trend and seasonality).

In the above graph please note that
Period 1 to Period 4 - Year 2016
Period 5 to Period 8 - Year 2017
Period 9 to Period 12 - Year 2018
Period 13 to Period 16 - Year 2019
From the trendline, it is evident that over the 16 periods(4 years) the number of employed individuals increased. This shows a positive trend line.
Regarding the seasonality, we can clearly observe that in every year Quarter 3 shows a decline in the employed individuals compared to Quarter 2.
